King Aguila, Vhong Navarro and his best friend, Junior Iskalibers Mura enroll in the entrance exam for an academy that trains secret agents, chasing a dream inspired by King’s idolization of Tony Falcon Tony Ferrer. Under the stern supervision of Col. Cynthia Abordo [Pokwang], they are admitted but quickly prove themselves to be the least competent recruits in the batch, stumbling through drills and schemes with comic mishaps at every turn.
Inside the academy, King meets Mary Grace Talagtag [Mariel Rodriguez] / Agent 690, a newly minted recruit who quietly harbors a crush on him. She asks King out on a date, and a tense restaurant moment leads to a misunderstanding: Mary Grace suspects he’s a playboy when he appears to be embracing another woman, and she leaves with mixed feelings. After graduating alongside King, Mary Grace accepts West Point training, leaves the country with a bitter impression of King, and returns years later as the country’s top agent, her memories of their time together colored by ambition and rivalry.
King, meanwhile, is handed three cases to solve but fails at every turn, and his prospects within the agency dwindle until he is demoted to a clerical post. He and Junior end up graduating as “reserve agents” who temporarily work as janitors in the agency headquarters, a humiliation that fuels their stubborn determination to prove themselves.
The plot thickens when the Philippines’ most important artifact, Lapulapu’s bolo—the weapon historically linked to Magellan’s defeat—vanishes from a museum. The museum’s curator, Minerva Castillo, contacts the agency with a sensational claim: the dagger can turn water into crude oil. As the top agent, Mary Grace expects the assignment, but Tony Falcon [Tony Ferrer] pushes to keep King in the loop, prompting a reluctant reunion between the two. With Junior’s help, King nearly recovers the dagger but loses it again, driving Tony into a period of despair that culminates in a sudden fall into a manhole. Col. Cynthia Abordo decides to remove King from the mission, and Tony’s supposed “death” becomes a wakeful crisis for the team.
In a bold ruse, Junior pretends to be Tony’s ghost, pressuring Cynthia to reinstate King. The plan succeeds, and Cynthia pairs King with Mary Grace to retrieve the dagger. The quest takes them across dangerous hideouts: first to Mustafah Saleh’s Floridablanca lair, then to Leah’s seaside resort, where the dagger is briefly auctioned away. Leah is shot by King, but Minerva steals the dagger again and flees by boat with her goons. Distraught, King mourns Tony at the manhole, only to discover that Tony had faked his death to push King to excel, a revelation that re-energizes him.
An investigation reveals a shocking twist: Minerva, with a past entwined with Purubutusan’s schemes, is connected to a shocking twist in which she was a monkey genetically engineered to become human by Purubutusan. Fueled by this discovery, King and Mary Grace infiltrate Purubutusan’s lair, where Mary Grace is captured and King is temporarily paralyzed. After recovering, he returns with Cynthia’s help to defeat Purubutusan and his henchmen, rescue Mary Grace, and escape just as the lair explodes from a timed device. King is promoted to a full agent and the two agents become a couple, with Tony reappearing to everyone’s surprise.
In the epilogue, Cynthia reveals that a corrected translation of the inscriptions on Lapulapu’s dagger indicates it actually produces cooking oil rather than crude oil, a realization that leaves her frustrated but the mission’s success intact. The tale blends action, humor, romance, and a touch of science fiction as it closes on a note of renewed partnership and a brighter future for the two agents.
